Beseler 45MX head on DeVere 504 chassis

[Deryck]

Hi ,

I'm from Denmark and I recently aquired the chasis of a 'DEVERE 504' bench enlarger. Just the column, baseboard, negative carrier stage,
bellows and lens stage - no head.

I have a 'BESELER 45MX' enlarging head containing the double 4" x 5" condenser set - just the head. It is now my intention to marry the BESELER head to this awesome DEVERE chasis. The mechanics of the operation should not present an insurmountable problem as I have access to various materials, and a fairly well equipped workshop.

I work solely in the 4" x 5" format, through a 150mm. enlarging lens on an old, but well maintained Omega D2. For the above enterprise to be successful I will need to know the optimum height at which to fix the BESELER lamphouse above the DEVERE negative stage. (collimation?)

My problem is: I don't know what this distance should be!

My quesion is: Would anyone owning a 'BESELER 45MX' enlarger which is set up for the 4" x 5" format, be kind enough to measure the distance in millimeters between the lower condenser on the lamphouse, and the negative stage (I think there are a set of bellows between the lower condenser and the negative stage on the BESELER 45MX to facilitate format changes) and then post the info here on APUG? I could then apply this distance directly to fixing the head and chassis of my two enlargers together. Or...if anyone would care to contribute their knowledge - empiric or otherwise - to solving this problem, I would be most grateful.

Thanks for your time,
Deryck

(there was a url link here which no longer exists)

4x5 film, the head needs to sit as close to the negative stage as possible.

measuring from that point.

3 1/4 x 4 1/4 is 1.25 inches
2 1/4 x 3 1/2 is 2.25 inches
2 1/4 x 2 1/4 is 3.5 inches
35 mm is 4 3/4 inches

(sorry it's not in millimeters)

Wow!
That was FAST. Thanks man. Problem solved.

Mange Tak! (means what you think it means)

Well, I should say that the info came from Ann Clancy, who actually bothered to measure when the question was asked in the earlier thread.

You're welcome, though.
